BUILDING STRUCTURE Filed Dec. l5, 1928 2 Sheets-Sheet l A TT ORNE Y Patented Oct. 14, 1930 PATENT OFFICE FREDERICK M. VENZIE, OF PHILADELPHIA, PENNSYLVANIA BUILDING STRUCTURE Application filed December 15, 1928.' Serial No. 326,310. i

This invention, generally stated, relates to a` building structure and has more especial relation to means for supporting cementitious slabs forming a ceiling construction.

5" The leading object of the present invention may be said to reside in the provision of means whereby unskilled labor may more rapidly and efiiciently erect ceiling slabs of cementitious material thereby to reduce 'lo building costs.

A further object of the present invention is to provide a structure of the character stated which not only is entirely constructed of fire proofing material but is sound proof L and very strong and very cheap to erect.

A further object is to provide the slab ends with portions for completing fire proofing of the ceiling and at the same time to provide efficient crack preventing portions between o adjacent slabs.

Other and further objects of the present invention reside in the provision of the general arrangement, combination and connec- 5 tion of parts for attaining the results sought by the foregoing objects.

The invention consists of the novel construction hereinafter described and finally claimed.

30 The nature, characteristic features and scope of the invention will be more fully understood from the following description taken in connection with the accompanying drawings forming part hereof, and in which z 5 Fig. 1, is a fragmentary view in longitudinal section of a ceiling structure cmbodying the invention.

Fig. 2, is a view in horizontal section taken upon the line 2-2 of Fig. 1.

Fig. 3, is a view in section taken upon the line 3-3 of Fig. 2.

Fig. 4, is a view in section line 4-4 of Fig. 2.

Fig. 5, is a fragmentary sectional view in 45 horizontal section illustrating a detail of construction; and

6. is a view in perspective of one of the slab hangers embodying the invention.

For the purpose of illustrating my inven- 5@ tion l have shown in the accompanying drawings one form thereof which is at prestaken upon the ent preferred by me, since the same has been found in practice to give satisfactory reliable results, although it is to be understood that thevarious instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of the instrument-alities as herein shown and described.v

Referring now to the drawings in detail, the reference numeral 10 designates the side walls of a building of any suitable structure. The'reference numeral 11 designates a iiooring usually of concrete supported by which are metal hangers 12. These hangers 12 carry the channel irons or crossbeams 18. The channel irons or cross-beams 13 in turn are arranged to support the cementitious slabs, which are designated 14. The means for suspending the slabs 14 with respect to the channel irons or cross-beams 13 is taken care of by clips`15, as shown in Fig. 6, and a detailed description of which will presently appear. Each slab 14 has embedded therein a pair of spaced, longitudinally arranged metallic rods 16 which extend the entire length of a slab. The ends of each rod 16 are bent first upwardly at 17 and then downwardly at 18, see Fig. 4. Adjacent each downwardlv extended end 18 of a rod 16, a block or slab 14 is cut away as atY 19 so that the extended end 18 which is hook-shaped is exposed. In addition to being cut away as at 19 all of the sides of the slabs are bevelled as at 20, see Figs. 4 and 5.

- Referring now to the manner of suspending the slabs 14 from the beams 13 by means of the clips 15 I will first describe in detail these clips, reference being had particularly to Fig. 6. A description of one of sufiice since they are all duplicates of one another. Each clip comprises a single piece of thin metal forming a strip which is relatively broad and bent over at its tor to form a hook- ,y This hook-like portion 21 is like portion 21. fitted over the upper end of the channel iron 13. as clearly shown in Fig. 4, with the pendant portion 22 extended down through the opening 19 in a slab, as clearly illustrated in Fig. 5. The lower portion of the pendant part and these clips will L a very rsimple and eiicient of the clip is cutaway as at 23 yto leave a vertically disposed nib 24. The cut away portion 23 and the nib 24 form a hook-like part to engage beneath the turned down portion 18 of a rod 16. This is best seen in Figs. 4 and V5. The nib 24 prevents the part 18 from being disengaged from the slot 23. Upon the same side ofthe clip l5 as 'the slot 23 is another slot 25 anda horizontally disposed nib 26. The,V

nib 26 is arranged to engage beneath the bottom of the channel iron 13, see Fig. 4. This arrangement and construction of parts makes ing a block or slab 14 and with the-hooked portion 21 engaging over the top of the slab 13 and thenib 26 engaging beneath the bottom l ofthe slab 13 vertical movementis prevented,

thus making for a neat and tight fitting conhook-like ends of said rods, said hangers each being provided with a cut away portion to engage the hook-like ends of said rods, said hangers also being provided with horrzontally extended lips for engaging beneath said channel beam to prevent vertical movement of the hanger, and a filling of cementitiousmaterial arranged between the opposed faces of said slabsto conceal said hooked ends of said rods.

K bodied in other specific forms without departing from kthe spirit or essential attributes thereof, and I therefore desire the present embodiment to be considered kin all respects as illustrative and not-restrictive, referencebeing had to the appended claims rather than to the foregoing description to indicate the scope of the invention.

lWhat I claim is f 1. In a building construction aV channel beam, a pair of cementitious slabs arranged below said channel beam, the opposedffaces of saidslabs being cut away, a metallic rod eX- tended longitudinally through each of said slabs,` the terminals of which are hook-'shaped and project into said'cut-away portions of said slabs; and metallic hangers suspended from said channel beam and engaging the hook-like ends of said rods, said hangers each being provided with a cut away portion to engage the hook-likeends of said rods', said hangers also being provided with horizontally extended lips for engagingbeneath said channel beam to prevent vertical movement of the hanger.
